Could papillary fibroelastoma in the tricuspid valve cause thrombocytopenia?

Cardiac myxoma and papillary fibroelastoma are the most common benign primary cardiac tumors in adults. In this brief report, we described a male patient with a mass in the tricuspid valve (papillary fibroelastoma as a result of pathology), who presented with thrombocytopenia and underwent tricuspid valve replacement. The patient was followed and treated by the hematology clinic due to thrombocytopenia, but a definitive diagnosis could not be made. The patient was incidentally diagnosed while being investigated for urinary stones. Thrombocytopenia improved in the postoperative follow-up. The successful surgical procedure, along with echocardiography and pathology images of the patient, was shared.
